One app tracks your whole parenting journey and treats pumping as a single log among many. The other does nothing but pumping — and does it deeper than anyone. We tested both for 30 days because moms who pump keep asking which one belongs on the home screen. The honest answer depends on how central pumping is to your day.
Wermom is a multi-category tracker: pregnancy weeks, feeds (breast, bottle and pump), sleep, diapers, growth percentiles and milestones, backed by a 16-person medical advisory panel and spanning roughly pregnancy through age three. Pumping is one log type inside a much larger record — competent, integrated, but not the centre of the product.
Pump Log is a single-purpose pumping app. It exists to answer one set of questions extremely well: how much did I express, from which side, at what time, and is my supply trending up or down? It logs sessions in seconds, charts output over days and weeks, helps you spot the times of day your supply is strongest, and is purpose-built for the exclusive pumper and the return-to-work mom managing a stash. It does not track sleep, diapers, growth or milestones, and it does not want to.

The total favours Wermom, but read the edge column closely: on the one dimension that matters most to a dedicated pumper — pumping depth — Pump Log wins 9.5 to 6.5, and it is cheaper. Wermom wins the overall contest by being good at twelve things; Pump Log loses the overall contest while being the best app in the world at one of them. For the right mom, that single category outweighs the other eleven.
Pump Log wins the dimension it was designed for, and it is not close: if your day is structured around the pump — an exclusive pumper, a mom triple-feeding through a supply issue, or someone building a freezer stash before maternity leave ends — its analytics tell you things Wermom's feeding module simply does not surface. The per-side output history and the "your supply peaks at 6 a.m." kind of insight are genuinely actionable, and at its price it is one of the best-value apps in our entire universe. We are not going to pretend an all-in-one tracker out-pumps a pumping specialist; it does not.
But the question most moms actually ask is broader than pumping, and for that broader question Wermom wins. Pumping is usually a phase inside a longer journey that also includes sleep regressions, solids, growth checks and milestones — and keeping all of that in one timeline beats stitching together a pumping app and three others. Wermom's unified feeding timeline puts pump sessions next to breast and bottle feeds, so the bigger feeding story stays in one place even if the per-session depth is shallower. For pumping guidance itself, the Wermom advisory panel's lactation guidance adds clinical context that a pure-analytics tool deliberately leaves out.
Prices cross-checked on the App Store and Google Play on 2026-05-30. Note the structures differ: Wermom is an ongoing subscription that covers many categories, while Pump Log is a near-free app with a small one-time unlock for one category. On pure dollars-per-feature within pumping, Pump Log is unbeatable; on dollars-per-feature across all of parenting, Wermom earns its subscription.
We ran both for 30 consecutive days on iPhone 15 and Pixel 8, logging real pumping sessions in parallel alongside the rest of a baby's day. We judged Pump Log in the conditions it is built for — multiple sessions a day, tracking supply over weeks — and judged Wermom on whether its pumping log was good enough to keep a pumping mom from needing a second app. Scores reflect lived use, not spec sheets, and the per-dimension edge column matters more than the totals when the two products have such different scope. For moms outfitting a pumping routine, the storage-and-flange gear in Wermom's milk-storage essentials pairs with either app.
By the second week the division of labour was clear. For our combination-feeding stretch, Wermom was the app open all day — a pump session logged here, a nap there, a growth check, a milestone glance — and the pump entries blended into a feeding picture we could read at a glance. That integration was the point: we never had to ask "where did I record that?" because everything lived in one timeline. What Wermom could not do was tell us, with any precision, whether the left side was under-producing or which time of day was our most efficient window.
Pump Log answered exactly those questions. Switching to it for a few exclusive-pumping days, the per-side history and the supply trend chart turned a vague worry ("is my supply dropping?") into a clear line we could act on. The trade-off was just as clear: it had nothing to say about anything other than pumping, so the rest of the baby's day went unrecorded unless we kept a second app running. The lesson of 30 days is that these two fail in opposite directions — Wermom is shallow on pumping depth but broad on everything; Pump Log is deep on pumping but blind to everything else. Which failure you can live with is the whole decision.
Wermom takes the head-to-head at 8.1 to 7.2, and for the broad audience of moms who pump as one part of a bigger journey, it is the right home-screen app. But this is a genuine honest split: if pumping is the centre of your world right now, Pump Log out-performs Wermom on the only dimension you care about, and it costs a fraction as much. Buy Wermom for the whole picture; add or substitute Pump Log if the pump is the picture. For many moms, the smartest answer is both.
